A distillation column unit consists of a partial reboiler, a column with seven equilibrium plates and a total condenser. The feed consists of a 50 mol % mixture of benzene in toluene. It is desired to produce a distillate containing 96 mol % benzene, when operating at 101 kPa.a. With saturated-liquid feed to the fifth plate from the top, calculate: (1) Minimum reflux ratio (LR/D). (2) The bottoms composition, using a reflux ratio of twice the minimum. (3) Moles of product per 100 moles of feed.b. Repeat part (a) for saturated-vapour feed fed to the fifth plate from the topc. With saturated-vapour feed fed to the reboiler and a reflux (L/V) of 0.9, calculate: Bottoms composition, (2) Moles product per 100 mole of feed.
